The French striker came off the bench to make his first appearance since February and netted the Gunners’ third goal to help wrap up a 3-0 victory against the Potters at The Emirates on Sunday.
Aubameyang had scored both of Arsenal’s goals, one from the penalty spot and another from open play, to help the Gunners take control of the game.
And rather than trying to complete his hat-trick from the spot, Aubameyang opted to hand penalty-taking duty to Lacazette at The Emirates.
Asked about his decision to let Lacazette take the penalty, Aubameyang told Sky Sports: “I know that Laca is back and I’d scored twice, so I wanted to let him score.
“It’s normal. I think it’s good for his confidence, and that’s why.”
Lacazette was making his return from a knee injury which has kept him out of action since 10 February.
The win left Arsenal in sixth place in the Premier League table and five points behind fifth-placed Chelsea FC.
The north London side will now switch their attentions towards their crunch Europa League quarter-final clash against CSKA Moscow at The Emirates on Thursday night.
Arsenal’s best hope of qualifying for next season’s Champions League will be to win the Europa League title this term.
